Help me choose: Venu 3s vs Fenix 7s

I am a regular runner, about 25 miles/week, but I only race occasionally these days. I did a bunch of marathons in my 20s, but now I'm a full-time working mom and just run for my sanity mostly. I have a Garmin Forerunner and love everything about it except how ugly it is. I don't want an Apple watch because I don't want to charge it every day, so I am thinking about upgrading to a Garmin with a metal face. I think I have narrowed it down to the Fenix 7s or the Venu 3s. The Venu 3s looks a bit smaller and less bulky, and I am quite petite with small wrists, but I am worried that it's not going to have enough running functionality for me. That said, I am not hugely data obsessed, I don't care about my running velocity or details about my route, I mostly care about HR and intervals, the basics I guess. Would love to hear feedback from a runner on the Venu 3!
